IMPROVEMENT IN' FLOUR-BOLTING- APPARATUS.

The Schedule referred -to in these Letters Patent and making part ofthe same drawing and t-o the letters of reference' marked thereon making a part of this specicatiou.

The nature of my invention consists in the construction and arrangement of a.ilour-boltin'gl apparatus, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a longitudinal vertical section, and Figure 2 is a transverse vertical section of my bolting apparatus. v

A represents a box, of suitable dimensions, in which the bolt B is placed'.

The bolt is made in any of theknown and usual Ways, and its shaft, C, has a stationary bearing in the front end of the box, while the other end of the shaft passes through a vertical slot in the rear end of the box, and is, outside of the box, provided with a cogwheel, D, or other suitable gearing, to be connected with the mechanism for rotating the bolt.

In the box-lid E, at the rear end, is a hopper, G, which comes directly over a conductor, H, in the box,

said conductor leading into the bolt, and its mouth surrounded bgzthehead I, which is stationary on the inside of the bolt, the bolt revolving around the same.

By this arrangement the bran is kept from passing out at the end, and, at the Sametime, creating a breeze to cool the Hour.

On the upper'end ofl the' bolt-shaft C is a toothed l wheel, J, which bears on an inclined plane, K, within the box at the rear end. 'lhis wheel is so constructed that, when the bolt revolves, it drops from one-half to 'an inch, shaking and jarring tlie bolt, so that all the flour may pass out and drop into the meal-chute, and, at the saine time, cooling the Hour.

Having thus fully described my invention,

`What I .claim as new, and desire to secure. by Letters Patent, is-

1. The stat-ionary head I, surrounding the mouth of thecouductor H, and placed within the end of the bolt, substantially as and for the purposes herein set forth.

2. Thearrangenient of the bolt B, shaft O,l1ead I, conductor H, toothed wheel J, and inclined plane K, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing, I have herennty set my hand this 14th day of March, 1870.
